Paul, For the Questions we are doing for 'The Equilibrium Constant', do we need to put the units in our answers? (Are the units for concentration and the Keq in moles?)
I asked Paul about this and he said we don't have to worry about units (for the first page) since they don't give units for Keq.. But for concentration the units are in moles/L....
Sweet, thanks!
In questions that state the volume of a container, and then give you the concentrations, do we assume the concentrations they give us are in mol/L, or do we assume the number they give us is the number of moles, and we need to convert to mol/L?
I think if they have concentrations brackets [N2], then they are already in mol/L so you do not have to calculate it. for example in question 6 on page 1.
Thanks Shama!! :)
For Questions (g) and (h) that we have to do on page 519.. where do you find the Keq for CaOH because it is not in the back of the book and that is making it rather difficult to compare to the results collected...
I got from the web. at 25 C, it is 5.5 X 10^-6.
Hey guys i checked some other sites and theres a mixed response of what shama said and 7.9 x 10^-6
For page 513, f) What kind of anomalies do they mean.. Does different amount of product formation in the filtered solution count as an anomaly.
I wrote about there being the presence of ions in the final solution (calcium ions and sulphate ions present in addition to the calcium sulphate precipitate) which was not identified in the net ionic equation.
